SMOKING TUBE OR IMPLEMENT.

Specification of Letters Patent.

Patented June 29, 1915.

Application filed April 9, 1915. Serial No. 20,184.

To all whom it may concern Be it known that I, CALEB C. DULA, a citizen of the United States, residing at Yonkers, in the county of Westchester. and State of New York, have invented new and useful Improvements in Smoking Tubes or Implements, of which the following is a specification.

My present invention relates to certain new and useful improvements in smoking tubes or pipes especially adapted for use in connection with prepared smoking cartridges orcharges.

. One object of the'invention is to provide a smoking implement of the class above referred to that can be comfortably and conveniently carried in the pocket of the user and which will take up very little room.

resting thereon.

Another, and very im ortant object of the invention is to provi e a smoking implement having simple and efficient-means within the bore of the bowl for anchoring an inserted cartridge therein in order to revent, accidental dislodgment 'of the carridge therefrom during smoking. Another object is to provide an implement that may be easily and quickly cleaned and wherein provision is made for a substantially straight draft directly from the mouth of the bowl to the mouth-piece of the stem.

A further object of the invention is to provide a smoking implement of the character described wherein the bowl and stem are in substantial alinement and wherein the said bowl is provided with a flat bottom wall intermediate its ends constituting a resting face for the implement when placed upon a flat sup orting surface, such as a desk, table or the ike, the said fiat wall being so arranged with relation to the mouth of the bowl and the stem or mouthpiece that both of these parts of the implement will be elevated above and out of contact with the supporting surface when the implement is Other more or less important objects will appear from a reading of the detailed description to follow taken in connection with the following drawing, which is illustrative of one embodiment of the invention, and wherein Figure 1, is a side elevation of a smoking implement made in accordance with the invc ti n- F g- 2, is a ott m p ie Fig. 3, is a vertical longitudinal section, Fig. 4, 1s a transverse section taken on the line 4--4 of 1. Fig.5, is a central vertical section of the bowl-portion of the implement showing the manner in which the tobacco cartridge is anchored therein, and Fig. 6, is a view similar to Fig. 5, showing a slightly modified construction.

Referring now to the drawing the reference numeral 10, designates the bowl of the implement, and 12, the stem. The bowl in the instance shown is cylindrical in form, and its body portion 13, tapers gradually from its mouth end to the point of attachment of the stem, where it terminates in a reduced neck 14. While I prefer to make the bowl of cylindrical shape, asshown, I do not wish to be restricted to this particular shape as obviously other shapes may be employed without departing from the spirit of the invention.

The body portion 13, of the bowl, is provided on its under side, and at a point intermediate its ends, with a flat seating or resting face or wall 15, which is preferably located in a plane below the plane of those portions of the bowl and neck at opposite ends of said face and also in a plane below the plane of the under face of the stem 12. As more clearly shown in Figs. 1 and 3, which illustrate the implement as having its flat seating face 15, resting upon a flat supporting surface, it will be seen that the forward portion of the bowl in advance of the flat seating face as well as the rear portion of the bowl, including the stem and mouthpiece, are elevated above and out of contact with said supporting surface, hence the mouth-piece is not likely to become contaminated nor is the heat of the bowl likely to burn or blister the supporting surface when the implement is resting with its flat seating face in contact with such a surface. Forthermore the flat seating-face, owing to its position with relation to the bowl, and stem, serves to support the implement in an upright position and prevents the tobacco or ashes from falling from the bowl.

The stem 12, is preferably provided with a push-fit connection 16, with the end of the bowl-part of the implement, as more clearly shown in Fig. 3, and by referring to said figure it will be seen that the draft opening or passage 17, in body portion 13, enters or intersects the bottom of the bore 18, .of the bowl at substantially the axis thereof,

and that the passage 19, of the stem 12, is in substantial alinement with the passage 17, hence the draft opening or passage from the bowl to the mouth-piece is a substantially straight one. This construction not only provides for a .free draft through the bowl and stem, and enables these parts to be more readily cleaned, but the arrangement of the passage 17, with relation to the central longitudinal axis of the bore of the bowl seems to cause the tobacco to burn more evenly.

In order to prevent accidental displacement of the inserted cartridge from the bowl of the implement, I prefer to make the wall of the'bore 18 of the bowl slightly tapering from the mouth end inward, so that the lower portion of the bore will be of less diameter than the entering portion which I have shown as provided with a'flaring mouth 20, to more readily facilitate insertion of the tobacco cartridge 22, into the bowl. I also prefer to provide a depression in the wall of the bore of the bowl which, in the instance shown in Figs. 3 and 5, is in the form of a circumferential groove 21, into which groove the inner end of the tobacco cartridge 22 may expand laterally, when forced into the bore, there being a shoulder 23, adjacent the forward circumferential edge of the groove which acts to compress the inserted cartridge at this point, an annular. stop or abutment wall 24 being formed adjacent the rear circumferential edge of the groove. The said stop or abutment 24 is formed a slight distanceforward of the bottom of the bore 18 and serves as a means for preventing the cartridge from being pushed too far down into the bore, thus leaving an enlarged chamber 25, at the base of the bowl between the end of the cartridge 22, and the bottom of the bore, into which the passage 17 opens centrally.

Instead of making the cartridge retaining means in the form of the circumferential groove, as described, I may employ simply the taperedwall before referred to, asmore clearly shown in Fig. 6. In this case, however, I prefer to retain the annular stop or abutment 24 so as to provide the chamber 25 between the end of the cartridge and the base of the bowl, as such a chamber arranged in the manner referred to,'s eems to kee the bowl cleaner and tends to cause the to acco to burn more freely, since a draft through the implement can act more freely through substantially cartridge.

By maklng the wall of the bore tapering in the manner described, it will be apparent that when a smoking cartridge of substantially the same diameter as the entering end of the bore is forced downinto that portion of the bore of narrower diameter, the said cartridge will fit so closely into the bore that it will not fall out, and, of course when,

the entire diameter of the in addition to the tapering wall referred to, the circumferential groove is provided in the wall of the bore, then the end of the inserted cartridge will expand laterally and thus effectually prevent accidental dislodgment thereof.

I prefer to locate the cartridge retaining means within the bore of the bowl in such a position that the cartridge will be engaged at substantially its extreme inner end so that it ate its ends, and the said stem and the mouth of the bowl beingfelevated above the plane of said flat resting face.

2. As a new article of manufacture, a smoking implement especially adapted for smoking repared cartridges, comprising a bowl, an stem in substantial alinement and of gradually tapering contour from end to end, said bowl having a flat resting face on its lmder side at a point intermediate its ends and the parts being so constructed and arranged that when the said flat face is resting upona flat supporting surface the bowl .and stem will be held elevated and free from contact with such surface.

3. A smoking implement comprising a substantially cylindrical bowl having duced neck at one end and a stem in substantial alinement with the bowl removably.

fitted to the neck, said bowl having a fiat resting face on its under side intermediate the ends of the neck and bowl respectively and said neck and bowl each curvin up- ;vardly and outwardly from the said flat ace.

.4. A smoking implement especially adapted for smoking prepared tobacco cartridges, said implement comprising a bowl and a stem in substantial. alinement and the bowl having a flat resting face on its under side, the bore of the bowl being tapered inwardly and provided with a rec'ess'to permit lateral expansion of a portion of the cartridge when inserted thereinjo prevent a reaccidental dislodgment of the cartridge therefrom.

5. A smoking implement especlally' adapted for smoking prepared tobacco cartridges, said implement comprisin a bowl and'a stem, the bore ofthe bowl aving a portion tapered inwardly to compress an inserted cartridge and being recessed beyond said tapered portion to permit expansion of the cartri go into said recess and thus prevent accidental dislodgment of the cartridge from the bowl.

6. A' smoking implement especially adapted for smoking prepared tobacco car- A tridges, said implement comprising a bowl and a stem in substantial alinement, the bore of the bowl being tapered inwardly to compress the cartridge and provided with a circumferential groove at the end of the tapered portion into which an end of an inserted cartridge may expand laterally to anchor the cartridge therein.

7. A smoking implement especially adapted for smoking prepared tobacco car-- v tridges, said implement comprising a bowl and a stem in substantial alinement, the

inner wall of the bowl from the mouth end inward to an inserted cartridge and said wall bein circumferentially recessed at the end of e tapered ortion to pansion of the end 0 the cartri ge, and an annular shoulder within the" bowl located adjacent the said circumferential recess, the said shoulder constituting a stopl or abutment to prevent the inner end of t e inserted cartridge from passing beyond the said circumferential recess.

In testimony whereof I have hereunto set my hand in presence of-two'sub'scribing witnesses.
